Supabase Rate Limits

Overview

Supabase enforces rate limits and quotas across every API surface — PostgREST, Auth, Storage, Realtime, and Edge Functions — and the numbers scale by plan tier. This skill gives you the exact per-tier limits, connection pooling via Supavisor, retry/backoff and pagination patterns, and dashboard monitoring so you stay within quota and handle 429 errors gracefully.

Prerequisites

• Active Supabase project (any tier)
• @supabase/supabase-js v2+ installed
• Project URL and anon/service-role key available
• Node.js 18+ or equivalent runtime
